+/**
+ * \brief Class for receiving signals.
+ *
+ * This is a convenience class for receiving signals when it is not worth
+ * the effort, or overly complicated to introduce a dedicated slot.
+ *
+ * Use as follows:
+ * \code
+ * SignalReceiver sr;
+ * sr.connect(some_obj, SIGNAL(someSignal()), SLOT(slot()));
+ * <do something with some_obj> ...
+ * if (sr.receivedSignal()) { // yes, signal was received
+ * }
+ * \endcode
+ *
+ * It is not possible to discriminate between different signals. Hence,
+ * use different signal receiver instances for different signals.
